Angular Bytes – June Edition

Your monthly dose of Angular tips, updates & debugging magic

Hey Angular devs! 👋
Welcome to this month’s issue of Angular Bytes, where we dive into practical tips, performance insights, and hidden debugging gems to help you build better, faster apps.

Debug Like a Pro: nx.getDirectives($0)

Tired of guessing which directives are applied to your DOM elements?

Here's a quick trick: In Chrome DevTools, inspect any Angular element and run:

nx.getDirectives($0)

Instantly reveals applied directives (e.g., NgIf, custom highlight directives, etc.)
Great for diagnosing rendering issues or directive-related behavior.

Works in Angular v14+ with Ivy in development mode.

Performance Tip: Keep Your App Light

Angular apps can bloat fast. Here's how to stay lean:

• Use ng build --configuration production

• Lazy load feature modules

• Set ChangeDetectionStrategy.OnPush

• Tree-shake unused RxJS or Angular Material modules

• Analyze your bundle with source-map-explorer

Bonus: Serve your app with Brotli or Gzip compression for even faster loads.

Component Debugging Tip: ng.getComponent($0)

Another DevTools gem:

ng.getComponent($0)

Instantly access the live component instance of any selected element in Chrome DevTools. Perfect for checking internal state, inputs, and outputs on the fly.
